Fallout New Vegas For Xbox 360:

Feel the Heat in New Vegas! Not even nuclear fallout could slow the hustle of Sin City. Explore the vast expanses of the desert wastelands - from the small towns dotting the Mojave Wasteland to the bright lights of the New Vegas strip. See the Great Southwest as could only be imagined in Fallout.
Feuding Factions, Colorful Characters and a Host of Hostiles! A war is brewing between rival factions with consequences that will change the lives of all the inhabitants of New Vegas. The choices you make will bring you into contact with countless characters, creatures, allies, and foes, and determine the final explosive outcome of this epic power struggle.
New Systems! Enjoy new additions to Fallout: New Vegas such as a Companion Wheel that streamlines directing your companions, a Reputation System that tracks the consequences of your actions, and the aptly titled Hardcore Mode to separate the meek from the mighty. Special melee combat moves have been added to bring new meaning to the phrase "up close and personal". Use V.A.T.S. to pause time in combat, target specific enemy body parts and queue up attacks, or get right to the action using the finely-tuned real-time combat mechanics.
An Arsenal of Shiny New Guns! With double the amount of weapons found in Fallout 3, you'll have more than enough new and exciting ways to deal with the threats of the wasteland and the locals. In addition, Vault-Tec engineers have devised a new weapons configuration system that lets you tinker with your toys and see the modifications you make in real time.
Let it Ride! In a huge, open world with unlimited options you can see the sights, choose sides, or go it alone. Peacemaker or Hard Case, House Rules, or the Wild Card - it's all in how you play the game.

When the game works its awesome, unfortunately with the bugs game is worth nothing as its so annoying you will stop playing. I get crashes every 15 minutes now :(

Could not agree more, I only just managed to keep going long enough to complete the main quest after giving up on the side quests because of so many crashes.
Shame because it really could have been a good game.
